On a ship that no longer moved, the only thing that never stopped was the sound of something failing.

 

Eli Torres knew the language of those sounds. A sharp metallic tick meant a regulator about to seize. A slow vibration meant a pump running too long without relief. A faint hiss behind a wall panel meant something worse was coming soon. He listened the way a musician listened for the wrong note, then followed the noise and tried to make the ship hold together one more day.

 

A coolant pipe split just after artificial morning. The crack sounded soft, but Eli was already moving before the environmental sensors caught up. He sealed the seam with a careful bead from the welding torch and waited until the metal cooled.

 

“You always get there first,” a voice said behind him.

 

Eli turned.

 

Mateo hovered a few meters down the corridor in his chair, the antigrav ring beneath it humming gently.

 

“You were supposed to stay in quarters.”

 

“You say that every morning,” Mateo said. “If I listened, I’d miss the lesson.”

 

“There isn’t a lesson.”

 

Mateo drifted closer, studying the repair. “Sure there is. Everything you do is.”

 

Eli closed the maintenance panel and gathered his tools. Mateo hovered beside him, persistent.

 

After the accident, Eli had tried to keep his son away from maintenance work. The corridors were cramped, and systems failed without warning. Mateo had listened to every warning carefully.

 

He kept following anyway.

 

The collision had ended their journey in a single violent moment. Engines gone. Navigation ruined. Sections sealed permanently. Mateo had survived the corridor collapse, but he would never walk again.

 

The hover chair came later, printed from spare components and fitted with a salvaged antigrav ring. It gave the boy freedom. It also made it impossible to keep him away.

 

Mateo watched every repair Eli made.

 

“What gave the pipe away?” he asked.

 

“The sound.”

 

“What kind of sound?”

 

“Metal arguing with itself.”

 

Mateo nodded thoughtfully. “Noted.”

 

The ship creaked softly around them. Something else would fail soon. It always did.

Months passed. Eli repaired systems the way a medic treated wounds, one at a time, knowing none would solve the larger problem. The ship could not move. No signal would reach anyone who could help.

 

But people still lived here, and that meant the systems still mattered.

 

The heater in Medical failed first. Eli rebuilt the coil using metal from a pendant that had belonged to his wife. Warm air returned before the patients noticed the cold.

A food processor jammed in the galley. Eli replaced the contacts with copper from a small music player she once kept beside her bunk. The machine hummed again and produced something resembling breakfast.

 

Each repair made the ship slightly better.

 

Each repair left Eli with slightly less.

 

Mateo noticed every missing object. He never mentioned them, but he watched Eli’s hands carefully.

 

“You always pause before you start cutting,” Mateo said once.

 

Eli glanced at him.

 

“You’re deciding what you’re willing to lose.”

 

Eli said nothing.

 

One evening he crouched beside Mateo’s chair and examined the antigrav ring. A thin fracture ran through the stabilizer housing.

 

Mateo saw his expression. “Bad news?”

 

“The ring’s failing.”

 

Mateo looked down at the faint glow holding him above the deck. “That does sound inconvenient.”

 

“I’ll fix it.”

 

Mateo smiled faintly. “You usually do.”

One afternoon, frustrated voices drifted through the corridor outside the rec lounge. Mateo paused near the doorway while Eli worked farther down the hall.

Inside, several children stood around a silent fabrication unit that once printed toys from recycled plastic.

 

“It’s dead again,” a girl said.

 

Mateo studied the open panel. The circuits looked fine. The power supply did not.

 

He rolled away without saying anything.

Eli finished sealing a maintenance hatch and realized Mateo was gone. The faint sound of voices led him toward the rec lounge.

 

Children crowded the fabrication table. A small plastic bird hopped clumsily across its surface.

 

Mateo sat beside the machine.

 

The hover chair no longer hovered. Its antigrav ring was gone.

 

Eli saw the wiring inside the printer and understood.

 

“You took it apart.”

 

Mateo shrugged. “It wasn’t doing much under the chair except floating me around.”

 

“You needed that.”

 

Mateo glanced at the floor, now closer to him.

 

“Floating looks impressive, but it doesn’t fix anything.”

 

The little plastic bird hopped again, and the children laughed. The sound filled the lounge in a way the ship rarely managed anymore.

 

“You should’ve told me,” Eli said quietly.

 

“You would’ve stopped me.”

 

A small boy stepped forward holding the pieces of a mechanical watch.

 

“My grandfather gave it to me,” he said. “But the spin parts still work.”

 

Another child held out his toy rover.

 

“You can use this.”

 

Soon several treasures rested beside Eli’s tools. Bearings. Axles. Tiny polished rings from toys that once spun or rolled: things children had carried across the stars because they mattered.

 

Eli looked at the pile. Then at the kids.

 

“Looks like you’ve got parts,” Mateo said.

 

“Not enough.”

 

Mateo grinned. “More than you’ve ever had before.”

 

Eli set his tools down and began working. It wasn’t long before he mounted newly fashioned bearings beneath Mateo’s chair, small rollers that would glide along the floor if someone gave the chair a push.

 

When he finished, Mateo shifted slightly. “Moment of truth.” He pushed against the deck, and the chair slid forward a short distance.

 

Not quite far enough.

 

A girl behind him placed her hands on the back of the chair and gave it a gentle shove. Mateo rolled the rest of the way across the room, laughing.

 

The toy bird chirped again from the table. Mateo picked it up.

 

Eli stood beside his son and watched the tiny machine flap its plastic wings.

 

“Good repair,” Mateo said.

 

Eli watched the children crowd around the toy that worked again. Something tightened in his chest. “Yes,” he said. “A very good repair.”
